Work: Calculate the value of equation 3/(1+5%)+3*(1+1%)/(1+5%)^2+3*(1+1%)^2/(1+5%)^3 .
Question type: Mathematical calculation
Solution:
3/(1+5%)+3*(1+1%)/(1+5%)^2+3*(1+1%)^2/(1+5%)^3
=3/1.05+3*(1+1%)/(1+5%)^2+3*(1+1%)^2/(1+5%)^3
=3/1.05+3*1.01/(1+5%)^2+3*(1+1%)^2/(1+5%)^3
=3/1.05+3*1.01/1.05^2+3*(1+1%)^2/(1+5%)^3
=3/1.05+3*1.01/1.05^2+3*1.01^2/(1+5%)^3
=3/1.05+3*1.01/1.05^2+3*1.01^2/1.05^3
=3/1.05+3*1.01/1.1025+3*1.01^2/1.05^3
=3/1.05+3*1.01/1.1025+3*1.0201/1.05^3
=3/1.05+3*1.01/1.1025+3*1.0201/1.157625
=2.857143+3*1.01/1.1025+3*1.0201/1.157625
=2.857143+3.03/1.1025+3*1.0201/1.157625
=2.857143+2.748299+3*1.0201/1.157625
=2.857143+2.748299+3.0603/1.157625
=2.857143+2.748299+2.643602
=5.605442+2.643602
=8.249044
Answer:3/(1+5%)+3*(1+1%)/(1+5%)^2+3*(1+1%)^2/(1+5%)^3=8.249044
